Here's the pulse, documented by KirunaSwedish Observatory:
A small pulse is observed around 02:00 UTC (white box). It is
recognized also by the Italian stations.
A second pulse much stronger (red box) following the first up in
the daytime. It is not, however, detected by the Italian
stations.

UTC, during the end of second pulsation.
The propagation path
during the day does not allow the signal to reach the middle
latitudes, where the Italian
observatory is located.

In Sogliano station
SRS are also faintly visible:
they originate from a strong storm front that, on the night,
crossed the Mediterranean sea.
The first Schumann resonance is best seen in the right spectrogram
(IRA). Instead the pulse is stronger in the spectrogram of the
left (Sogliano).
This is because the coils are not oriented in the same
direction: the placement direction
of each one was chosen for warranty the best immunity to
interference, coming from the electricity distribution
network.
